  • Patent number: 4850403
    Abstract: An indicating funnel for filling a container through an opening is formed as two peripherally joined, coaxially arranged funnels, one nested within the other to define a cavity between adjacent funnel walls. A vertically movable fluid level indicator is reciprocatable between the funnels and behind a transparent wall portion of the exterior funnel for viewing between a first lowered position and a second raised postion. The indicator in its lower portion is operably associated with a float positoned within the lowermost portion of the cavity between funnels to indicate fluid level in a serviced container. The exterior funnel, at its intersection with an associated spout, optionally incorporates positoning flanges for maintaining funnel alignment and stability cooperatively with various sized openings. Additionally, the fluid level indicator may include a luminescent feature enabling enhanced visibility and a cap skirt portion lessening spill potential.
